Question: Water is flowing out of the frictionless nozzle shown in the following illustration, where p1 = 120 psig and the nozzle discharges to the atmosphere.
a. Show a control volume and all control surfaces with all forces labeled.
b. Find the resultant force in the bolts at (1) which is necessary to hold the nozzle on the pipe.
c. If mercury, sp. gr. = 13.6, were flowing through the nozzle instead of water at the same conditions, what would be the new resultant force on the bolts?
